PUMP-CONTROLLING SWITCH.

To all whom it may concern:

Be it known that I, CHARLES GAMER, a citizen of the United States, residing at Fort lVorth, Tarrant county, Texas. have invented a new and Improved Pump-ControL ling Switch, of which the following is a specification. i

`My invention relates to switches and more particularly to electric switches for automatically controlling a pump. and the object which will he autoand opened bv the rise and nlatically closed Cellars or )asemen'ts of fall of water.

A.buildings frequently need draining. It bcwines necessary to pump thel water out of such places, and as water might accumulate n1 sufhclent quantity to do considerable damage it is necessary to provide means to prevent the accnnlulation ot' water. It has been found to he advantageous to provide a pump and a motor to drive the pump.

The object of this invention is to provide a switch which will he closed hy the rising); of the water to start the motor to running and thus pump the water out of the hasement or other place and which switch will be automatically opened when the water is pumped out so that the motor will stop runnlng.

Other objects and advantages will he fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accoml'ianying drawings which form a part of this application and specification.

Figure 1 is an elevation of a pump and a motor for driving the pump and a switch for startingr and Stopping the motor. Fig. 2 is a detail View of the automatically actuated switch. Fig. 3 is an ordinary switch which is used in connection with the switch shown in Fig. 2. Fig. 4 is a horizontal section on the line :i1-'m of Fig. l. Fig. 5 shows a variation in the application ot the Switch. V

Similar characters of reference are used to indicate thc salue parts throughout the several views.

A motor 2 drives a pinion 8 which drives a cogr wheel 7. (lopr wheel 7 drives a shaft 6 which drives the pinion 5. Pinion 5 drives the cog wheel lland cog wheel l actuatcs the pump rod il of the pump 1. 'lhc` pump l is located in an ott-set or cavity in the basement so that the pun|puill be Specitcation of Letters Patent.

automatically primed by the water. A switch E) is used for starting and stopping the motor 2. A float 10 is provided and connected to a crank 11 by a rod 12. The crank 11 actuates a shaft 13 which is journaled in a bearing 14. The caring 14 is supported in nprights 15. A cog wheel or flexible sector 16 is rigid witlrthe shaft 13. This double sector drives two racks 17 and 1S which are mounted in and move vertically in grooves in the uprights 15. The racks 1T and 18 have arms 19 at their upper ends. 'lhe arms 19 lift alternatively the plnngers 2O and 21 of switch 9'. The plungers 20 and 21 are pivotally connected with a rocking har 22 which is rigid with shaft 23. The switch 9 is a knife switch. A rocking har 24 is rigid with shaft 23. Arms 25 a'nd 26 are rigid with the bar 24. Contacts 27 and 29 are attached to the interior of casing The contact 27 is electrically connected to the motor 2 by ay wire 30. A coiiperating switch 31 is connected in circuit. with the switch 9. The switch 31 is also a knift switch. Switch 31 and switch 9 are Velectrically connected by a wire 32. The other arm of the switch 31 is electrically connected to thc motor 2 by a wire 33. The switch 31 is connected to a supply source of electricity hy wires 34 and 35. The switch 31 is opened and closed by an ordinary key 362 The advantage ot' the switch 31 is that the switch can .he located at any distance from the Switch 9, as in an otlice, and the circuit can be opened and remain open when .there is no necessity of operating the pump and thus save the, expense of an electrician in connecting and disconnecting the circuit..

The operation is as follows: As the water rises in the cavity or offset 36, the float 10 will he elevated. By the time the water rises high enough to prime the pump, the rod 12 will raise the rack 17 by means of crank 11 and close the circuit and thus start the motor. As the water is pumped out., the float 10 will descend andthe rack 18 will he raised and will break the circuit and thus stop the motor. y

Figi'. 5 illustrates a-dillerent application of theY .switch Sl. The pump 1 may he uscd to pulnp water from a well or cistern to a tank 8T, using` the same motor 2. The switch in this application would he made to open the circuit wh'cn the water should rise to stop the pumping ot' water. .ls the water in thc tank 3T would he used the tloat would gradles 1.
